Abstract

Plasma imaging diagnostics plays an important role for laser ICF. Based on the urgent need to carry out high-resolution, high-throughput plasma diagnostics, grazing-incidence X-ray Kirkpatrick-Baez (KB) microscopes and normal-incidence EUV Schwarzschild imaging system were developed. The X-ray multilayer KB microscopes were successfully been applied in the physics experiments of SGII laser facility. Combined with streaked camera, the Mo-backlit implosion flow line of hollow Carbon-Hydrogen (CH) spherical target was obtained in SGII. The 4.75keV single-channel and four-channel KB microscopes were also developed for self-emission and short-pulse backlit imaging diagnostic of CH cylindrical target. In addition, according to the need of ultra-short laser pulse plasma diagnostics, the Schwarzschild imaging system working at 68eV was researched, and the physical experiments of hot electron transport with Schwarzschild imaging system were performed in SILEX-I laser facility.
